Using default value for Solr field boosting when field does not exist

My existing Solr 4.x instance has about 650k documents indexed. I just added a new field to the schema that will hold a number of votes given to the document that will be used in boosting the score. Until the first user up votes (or down votes) a given document, said document will not have that field defined. You can see this when viewing the document using the Solr Admin tool.

The field was defined with a default value but I think this only applies to new documents (or maybe reindexed documents) that do not have said field specified.

When I try to test out different boosting functions, I get the following exception back

  "error": {
    "msg": "can not use FieldCache on a field which is neither indexed nor has doc values: votes",
    "code": 400
  }

Is it possible to specify a default value to be used for boosting when the field does not (yet) exist in the document? My logic would be

This seems to related to your earlier question. Perhaps you can try the FuntionQuery as well

 q={!boost b=map(field,0,0,0,default_value) } your_query

This will boost based on the field value, and use default_value if the field value is null.
